summary Tms570ls series is the industry's first floating-point, lock step dual core vehicle microprocessor based on arm ® cortex-r4f processor. Based on two cortex-r4f processors, the microprocessor is specially designed to meet the requirements of the Inter【More】

Stellaris arm cortex-m4 microprocessor (called stellaris lm4f Series) can provide floating-point and various functions and peripherals. The series includes general MCU, USB, advanced motion control (up to 16 PWM output) and other application categories, and has a v【More】

Ti officially released stellaris MCU. The latest arm cortex m4f core of 65nm process is adopted, with the main frequency up to 80MHz. The whole system provides floating-point operation support. Because of the adoption of 65nm process, lm4f has considerable advanta【More】

Compared with St Cortex-M3, the typical advantages of Ti and St Cortex-M3 are as follows: 1. Ti's Ethernet interface is MAC + PHY, and St needs to expand PHY 2. Ti only has 3 serial ports, ST has 5, stm32f2 has 6 3. The ADC of Ti is 10 bits, wh【More】

Many people have encountered the problem that debugger can not connect to STM32, whether it is j-link of IAR, ULINK of KEIL, or ST link of St. When this problem occurs, the debugging software will prompt that the connection with Cortex-M3 cannot be established, the【More】
